.To all whom, it may concern:

Beit known that we, IVALTER A. PECK and RICHARD A. BRIGHT, of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Cigar-Trapping Machines, of which the following is a specification.

In the employment of wrapping-machines for the manufacture of cigars it is very desirable to have the machines so constructed as to provide for the-proper adjustment of the cigar-rolling devices to suit the various contours, diameters, and lengths of cigars to be manufactured, so that a single machine by adjustment alone can perform every grade of Work. Heretofore there has been no machine made which in itself has been capable of said adjustment, and the requiredchange in form of the'rolls has only been eifected by means of changeable rigid rolls or roll-sections Which have the form desired, thus rendering it necessary for each cigar-wrapping machine to be supplied with numerous sets of rolls or roll-sections, which are to be arranged in the machine from time to time, as required, a considerable length of time being thus consumed in making the required change by the removal of the previously-employed rolls or roll-sections and substituting others therefor. j

It is the object of our invention to provide a ci gar-wrapping machine in which the cigarforming roll or a section thereof is made capable of the adjustment required without necessitating the removal and substitution of parts.

Our invention consists in a flexible roll or roll-section which is adapted to be supported for revolution in a curved or deiiected posi- 4o:tion, with means for adjusting the degree of curvature or deflection to properly embrace al cigar-bunch of any desired contour and roll the iinal wrapper thereon.

It also consists in improved means for changing the capacity of the rolling-chamber between a series of flexible cigar-forming rolls to provide for the manufacture of cigars having different diameters.

It also consists in improved means for changing the length of the rolling-chamber between a series of flexible cigar-forming rolls to provide for the manufacture of cigars having different lengths.

Figure 1 represents a vertical longitudinal section of a cigar-wrapping machine embodying our improvement. Fig. 2 represents a vertical transverse section taken in the line 0 o of Fig. l. Fig. 2u represents a vertical transverse section taken in the line a: Fig.

3 represents an endview of the supporting-A bar and adjustable bearing for supporting the upper roll of the series. Fig. 4 is an enlarged detail section of theroll. Fig. 5 is an enlarged detail section showing tbe deflected core and friction-roller adapted to change the contour of the rearward section of the roll. Figs. 6 and 7 are detail views showing modifications in the construction of the roll and in the means for supporting the same.

In the accompanying drawings, A is the base-plate of the machine; B, the standard which supports the driving-shaft C, and the series of flexible rolls D D D. vThe drivingshaft O is made hollow to receive the sliding forcer E, as usual in cigar-Wrapping machines, and is provided with the operating-handle F, attached to a suitable arm or wheel G, located upon the rearward end of the shaft. The shaft O is properly held against endwise movement in its bearing c by means of the adjustable collars a and b, which are placed at the opposite ends of the said bearing. The projecting forward portion of the shaft C is provided with a collar d, at the inner side of which is placed the loose frusto-conical or pyramidal piece e, and upon the'forward end of the shaft C is placed the adjustable sleeve f, which is secured to 'the said shaft by means of the set-screw g, the point of which enters the longitudinal groove hin the shaft. Upon the rearward end of the sleeve f is placed the collar t', and betweeny4 the collar t' and the flange 7' upon the sleeve f is placed the gear 7.a, the collare being secured to the sleeve f by means of the set-screw Z, and the gear 7c being also secured to the sleeve f by means of a steady-pin orotherwise. tending back from the standard B, is pivoted of the series, the said lever being adapted for operation to raise the said upper roll D from the lower rolls D D of the series by means To the arm m, eX-

l the lever H, which supportsthe upper roll D IOO of a treadle, which may be operatively connected with the lever H by means of the connecting-rod I. Vithin a slot fn, made in a forwardly-directed lateral projection o of the lever Il, is pivoted the socket-piece J, within the socket p of which is secured the rear end of the curved or deflected core K, which serves to support the tuck-forming end of the roll, the said core being adj ustably held within the socket pby means of the set-screw. q, Upon the core K is placed the adjustable tapering or wedge-formed piece r, which is secu redin position upon Yfhecore by means of the setscrew s. The core K is provided with an inwardly-direc ted deflection tand a corresponding outwardly-directed deflection u, upon which may be placed a friction-roller a, as shown in Fig. 5, the forward end portion of the said core being preferably in line with the shank portion fu. To the forward end of the lever Il is also attached the bar L, which serves to properly support the forward end of the roll D', and at the under side of the bar L is secured the spring yw, which is fastened to the said bar by means of the screw or, and at its forward end y rests upon the upper side of the shank o of the core K. The forward endl of the bar L is provided with a curved or inclined slot z, within which is placed the screw a', which serves to fasten the bearing-core M adj ustably to the bar L, the said core being secured to the arm b', which engages with the said screw, and by means of the said screw and slotted arm the core M is made capable of angular adjustment with reference to the axis of the cigar-rolling A pocket, so as to change the curved or deflected form ot' the forward flexible portion or section of the cigar-forming roll to conform to the desired contour of the head of the cigar. The roll D may be preferably made in sections, as t2 t3, the forward section t2 being provided with the tip c', which -is made of rigid material and loosely [its the angularly-adjustable core M lto revolve thereon, and to the tip c is attached ythe flexible wire coil clrfwhich covers the vacant space between the adjacent ends of the cores K and M, and which is preferably made in tapering form t-o correspond generally with the taperi'ng form of the head of. the cigar. The enlarged inner end of the flexible wire coil CZ is also provided with the attached Ahollow tip e', which has an adjusting set-screw f. The rearward section 3 of the roll D` is provided with the gear g', to which is attached the flexible wire coil 7L', connected to the sleeve 1l', which revolves upon-the inwardly-deflected portion t of the core K, and to t-he yforward end of the sleeve t" is attached the wire coil j', which is preferably made in tapering form to correspond generally with the taperingv form of the tuck end of the cigar, and `to the forward end of thewire coil j is att-ached the tip 7c', which loosely fits the forward portion c of the bearing-core K, the said portion fu being preferably about parallel with the axis of the cigar to be rolled in the machine. The bend m2 7of the core K is arranged to bear against the inner surface of the wire coil j at the upper side of the said coil, and thus the adjusted position of the bend co2 relatively to the said inner surface of the coil by the endwise movement of the core can be made to change the contourot' the roll-section t3. The tip 7c is provided with the forwardly-projecting hollow stem Z', which loosely enters the cavity of the tip e of the forward portion 152 of the roll, the said tip e being made adjustable upon the stem Z of the tip 7c by means of the set-screw f and between the adjacent ends of the flexible roll-sections t2 and t3 is placed the compressed spiral spring m', which will serve to piece out the roll adjustably between the said sections. Thus as the shoulders of the tips 7a and e are brought nearer to each other by the proper adjustment of the said tips the spring m will be compressed, and upon adjustment in the opposite direction will be extended so as to maintain a rolling action upon the surface of the cigar between the adjacent ends of the roll-sections t2 and t3. The gear g engages with the gear 7c, which is adjustable upon the shaft C, the gear g being made to partake of the adjusting movement of the gear 7c by means of the collar t' and flange j. The lower rolls D D of the series are supported from the projecting ears o2 and 03 of the standard B, and are constructed and heldin the same manner as the upper roll D', above described, and whenever the series of rolls are properly closed upon a cigarbunch the rotation of the shaft C, by means of the handle F or otherwise, Vwill cause the rol-ls D D D to revolve in the same direction with each other, thus imparting rotation tothe inclosed bunch for rolling on the wrapper. Y

Vhenever Vit is desired to adj ust the machine to change the form of the head of the cigar, the screw a is to be loosened and the bearing-core M set at the proper angle to give the required form to the flexible roll-section t2 and secured at said angle, by again tightening the screw a', and whenever it is desired to make adjustment to change the length of the cigar the said adjustment can be effected by properly adjusting the tips e and 7c by means of the screw f and making the proper corresponding adjustment of thev gear k upon the shaft C bymeans of the screw g and also moving the bearing-core K back farther into its socket in the pivoted piece-J and whenever it is desired to make the adjustment to change the contour of the ltuck end of the cigar the endwise adjustment of thecurved or deflected core K alone -by changing its position within its I"socket p and the wire coil j willcause `the required change in the curve of the bearing-surface of the rollsection t3, and to changethe diameter of the cigar the proper adjustment of the tapering piece 1' upon the bearing-core K by means of the set-screw s will cause the required angu- IIO lar movement of the spring-operated bearingcore K upon the pivot p to produce the required change, the teeth of the gears 70 and g interlocking sufficiently for this purpose.

An enlarged detail section of our improved cigar-forming roll is shown in Fig. 4, in which the bend x2 of the core K is extended outward from the line of the outer surface of the portion n of the said core, and thus has Va greater effect in changing the contour of the roll-section for any specific endwise adjustment of the core, and in the detail section, Fig. 5, we have shown a preferable construction,in which a friction-roller a4 is employed instead of the outward bend 002, (shown in Fig. 4,) the outer portion of the periphery of the roller being made to extend outward beyond.

the line of the outer surface of the portion e of the core K.

A modification in the construction of the cigar-forming roll is shown in Fig. 6, in which the tip c2 of the forward flexible section of the roll is provided with a bearing-journal O instead of running upon the angularly adjustable bearing-core M, and in this case the bearing-.piecef2 is made angularly adj ustable` by means of the screw a.

Another modification in the construction of the exible roll is shown in Fig. 7, in which the roll is formed of the rigid sections '2 and 3'2, which are connected to each other by means of the ball-aud-soeket universal joint k2, the defiected section i2 being held at its forward end by means of the ball-and-socket joint Z2, so that the proper angular adjustment of the pivoted core K', by means of the tapering or wedge formed piece r, as before described, will serve to change the form and diameter of the cigar.
